This question over English-speaking came up in December, when San Luis Mayor Juan Carlos Escamilla challenged Cabrera's candidacy, and a court agreed with the mayor.

Varitaions of Arizona's law mandating that anyone seeking public office be proficient in English have been around since before statehood, and it made its way into the state constitution.

The Supreme Court's ruling notes that the state constitution calls for candidates to have "sufficient English proficiency to conduct the duties of the office without the aid of an interpreter."

"The most plausible and harmonious reading of the statute is that it requires a sufficient level of proficiency of the English language to conduct the duties of the office without the aid of an interpreter," the ruling says.

Even though there's no specific test for this language requirement, the court didn't find anything unfair about a linguistics expert who testified in trial court that Cabrera "could not adequately function as a Council member in the Council meetings."

If you check out the decision (which can be found here), you'll see that the court didn't find much to agree with in any of Cabrera's challenges to the law.

Still, it was an issue that probably needed a definitive answer -- you can read about some of the intricacies of the language issue in this New York Times story -- and Arizona has it's answer: your politicians will know how to speak English.
